Potential borderlands 3 plot points

I was reading the wiki and i found out tannis and zero are actually close seeing as how tannis knows zeros true identity and how they worked together in tales from the borderlands so i was thinking that perhaps in borderlands 3 tannis and zero are the antagonists of the game or zero is just a robot controlled by tannis based on the head for him in moxxis wedding day massacre which is not officially canon but who knows id like to see all the theories.
